Lost Letter Experiment

Description: Milgram’s Lost Letter Experiment tested how circumstances determined how helpful individuals would be to strangers. The test was whether strangers who found an apparently-lost, stamped, addressed envelope would place it in the outgoing mail. The results were found to be largely dependent upon the listed recipient. The study found that personal letters or letters addressed to favorable organizations were much more likely to be mailed than letters addressed to antisocial or stigmatized organizations.Show more
